A kind of LED flat lamp
Technical field
The utility model relates to a kind of LED lamp, especially relates to a kind of LED flat lamp.
Background technology
The LED flat lamp is a indoor illumination light fitting.Existing LED flat lamp generally comprises power supply, backboard, frame, LED light source, light-passing board and lampshade, wherein frame is with backboard split setting and be screwed and be connected, LED light source is fixedly installed on scuncheon, light-passing board is fixed on backboard and is positioned at backboard and the space of frame formation, and lampshade is positioned at the light-passing board outside and is fixedly connected with frame.With backboard split setting and be screwed and be connected, the restriction frame that required by screw hole and heat radiation can't be done very narrowly, thereby the LED flat lamp has been caused restriction, has reduced radiating effect, has reduced light-emitting area due to frame.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of good heat dissipation effect, the LED flat lamp that light-emitting area is large.
the utility model solves the problems of the technologies described above the technical scheme that adopts: a kind of LED flat lamp, comprise power supply, backboard, LED light source, light-passing board and lampshade, described power supply is fixedly installed on the outside of described backboard, described power supply is connected with described LED light source, the inboard surrounding of described backboard has been wholely set frame, described LED light source is fixedly installed on the inboard of described frame, described light-passing board is fixed on described backboard and is positioned at described backboard and the space of described frame formation, described lampshade is positioned at the described light-passing board outside and is fixedly connected with described frame.
Described frame is that described backboard pressing and bending forms.
Described LED light source is the LED lamp bar of a plurality of parallel connections, and described LED lamp bar pastes by heat conduction and is bonded at described scuncheon.
Compared with prior art, the utility model has the advantage of by backboard and frame integrally formed, the heat of LED light source can directly be delivered on backboard from frame, distribute by backboard, form good radiating effect, owing to not needing to arrange extra connector on frame, the thickness of frame can reduce greatly in addition, thereby has increased the light-emitting area of LED flat lamp;
When frame was the formation of backboard pressing and bending, technique was simple;
When LED light source is LED lamp bar, LED lamp bar pastes by heat conduction and is bonded at scuncheon, has reduced the installation difficulty of LED light source, has saved cost of labor.
Description of drawings
Fig. 1 is explosive view of the present utility model.
The specific embodiment
Embodiment is described in further detail the utility model below in conjunction with accompanying drawing.
Embodiment: as shown in the figure, a kind of LED flat lamp, comprise power supply 1, backboard 2, LED light source 3, light-passing board 4 and lampshade 5, power supply 1 is fixedly installed on the outside of backboard 2, power supply 1 is connected with LED light source 3, and the inboard surrounding of backboard 2 has been wholely set frame 21, and LED light source 3 is fixedly installed on the inboard of frame 21, light-passing board 4 is fixed on backboard 2 and is positioned at backboard 2 and the space of frame 21 formation, and lampshade 5 is positioned at light-passing board 4 outsides and is fixedly connected with frame 21.
In the present embodiment, frame 21 is that backboard 2 pressing and bending form.
In the present embodiment, LED light source 3 is the LED lamp bar of a plurality of parallel connections, and LED lamp bar pastes by heat conduction and is bonded at frame 21 inboards.
The utility model is due to backboard and frame are wholely set, thereby can reduce the thickness of frame, improved light-emitting area, in addition because frame is less to the restriction of light-emitting area, the light intensity of surrounding of the present utility model is also larger, can select a plurality of LED flat lamp of the present utility model to carry out independent assortment according to the actual illumination needs, obtain the LED flat lamp group of different shapes, the combination variation.
